TTC but anovulatory for almost a year....

Guys...I'm on the virge if giving up. Came off the pill May 2013. Had a period July 2013, and just brown spotting around the same time each month ever since. DH and I have been trying but it's virtually impossible with no cycle at all. Went to the doc and she didn't really make sense to me. I had to lose some weight which I did, still nothing, I'm taking progesterone pills hopefully that will kick start my cycle. Anyone had any experience with these? Any help is greatly appreciated. I'm getting really depressed. :(
